Single Source of Truth

A centralized repository where all design decisions live, ensuring consistency across all platforms and tools.

The Problem: Multiple Sources of Truth

Without a single source of truth, design tokens, components, and patterns are duplicated across different tools and platforms, leading to inconsistencies and maintenance nightmares.

Example: Color Tokens

Before: Scattered Definitions

CSS: #3B82F6
Figma: #2563EB
React: #1D4ED8

❌ Three different values for "primary blue" = inconsistency

After: Single Source of Truth

Design System: label-blue-05
↓ Used everywhere
CSS
Figma
React

✅ One token, consistent everywhere

Key Benefits

  • Consistency: Same design decisions everywhere, automatically
  • Efficiency: Update once, propagate everywhere
  • Quality: Single place to enforce design standards and accessibility
